Method Details

copy

public static void copy(InputStream in,
 OutputStream out)
                 throws IOException

Copy an InputStream to an OutputStream and close the InputStream afterwards.

Throws:

IOException

copyAndDoNotCloseInputStream

public static void copyAndDoNotCloseInputStream(InputStream in,
 OutputStream out)
                                         throws IOException

Copy an InputStream to an OutputStream and do not close the InputStream afterwards.

Throws:

IOException

close

public static void close(Closeable c)

Close some xStream for good :)

close

public static void close(ZipFile file)
                  throws IOException

A special version of close() for ZipFiles, which don't implement Closeable.

Parameters:

file - the file to close. ZipFiles seem prone to file locking problems on Windows, so to aid diagnostics we throw, not swallow, any exceptions.

Throws:

IOException

getOutputStream

public static OutputStream getOutputStream(File outputDir,
 String relativePath)
                                    throws IOException

Throws:

IOException

writeOut

public static void writeOut(File outputDir,
 String relativePath,
 InputStream content)
                     throws IOException

Write the given InputStream to a file given by a root directory (outputDir) and a relative directory. Necessary subdirectories will be created. This method will close the supplied InputStream.

Throws:

IOException

writeOutAndDontCloseInputStream

public static void writeOutAndDontCloseInputStream(File outputDir,
 String relativePath,
 InputStream content)
                                            throws IOException

Write the given InputStream to a file given by a root directory (outputDir) and a relative directory. Necessary subdirectories will be created. This method will not close the supplied InputStream.

Throws:

IOException

zipUp

public static void zipUp(File rootDir,
 OutputStream targetStream)
                  throws IOException

Zip up all contents of rootDir (recursively) into targetStream

Throws:

IOException

zipUp

public static void zipUp(File rootDir,
 File targetFile)
                  throws IOException

Zip up all contents of rootDir (recursively) into targetFile

Throws:

IOException

jarUp

public static void jarUp(File rootDir,
 File targetFile,
 Manifest manifest)
                  throws IOException

Jar up all the contents of rootDir (recursively) into targetFile and add the manifest

Throws:

IOException

deleteRecursive

public static boolean deleteRecursive(File root)

Do rm -rf

unpackZip

public static boolean unpackZip(IFile zip,
 File outputDir)
                         throws IOException

Unpack the zip file into the outputDir

Parameters:

zip -

outputDir -

Returns:

true if the zip was expanded, false if the zip was found not to be a zip

Throws:

IOException - when there are unexpected issues handling the zip files.
